Tailed beasts.

The ultimate monster that has been handed down since ancient times.

Since ancient times, they have been a symbol of natural disasters.

It has a huge power that is beyond the reach of human beings.

The origin of the name is also due to the fact that they have a different number of tails, from one tail to nine tails, a total of nine-tailed beasts, which are strange lifeforms formed by the materialization of huge chakras.

Immortal and immortal.

Can only be sealed.

Shiraishi searched for all kinds of information about the Tailed Beast, and the classics on it all demonized the Chakra organism of the Tailed Beast, calling it a natural disaster.

In order to stop the tailed beasts from making trouble, someone needs to be used as a sacrifice to become a container for sealing the tailed beasts, that is, the human pillar force.

In the ninja villages of the five major countries today, each village has a human pillar weapon that seals the tailed beast.

Including Konoha where Shiraishi is currently located, there is also a tailed beast, and it is also the most powerful monster among the tailed beasts - the nine-tails.

The Nine-Tails is a giant demon fox with nine tails, once controlled by the ninja Madara Uchiha of the Uchiha clan, and then the first Hokage defeated Madara Uchiha, feeling that the power of the nine-tailed demon fox was too evil and powerful, so he took this opportunity to seal the nine-tailed demon fox and suppress it in Konoha.

The rest of the account was abruptly cut off at this point.

But knowing this is enough for Shiraishi.

Tailed beasts are lifeforms that are created after the materialization of chakras.

Possess the power of a natural disaster.

Thinking of the violent movement of a crane on that day, just looking at it from a distance, there is a sense of fear that cannot be defeated.

Shiraishi felt that there was nothing wrong with giving the Tailed Beast a symbolic name of natural disaster.

This is a power that is indeed difficult for humans to control.

The most important thing is that even if the Tailed Beasts are killed, they will be resurrected at random intervals somewhere in the ninja world.

Therefore, the Tailed Beast can only be targeted with the Sealing Technique.

Shiraishi looked at the closed glass pillar in the notch of the detection instrument next to him, and a cloud of chakra, an entity that emitted a light purple light, condensed.

"It's completely chakra, but it seems to have added a change in the nature of chakra with yin and yang attributes......"

According to what Shiraishi has learned, as well as the information obtained from practice, chakra is volatile.

In other words, if the chakra is materialized, after a while, the chakra will disappear on its own.

However, the tailed beast purely uses the entity chakra to maintain its form, but it will not continue to be in the chakra volatile state.

At least from what is known, tailed beasts do not have this persistent volatile nature.

"Is it because of the change in the nature of the yin and yang attributes? And there's something mysterious and unknown, which would have been hard to detect if I hadn't experimented with natural energy beforehand. ”

Bai Shi immediately stared at this group of tailed beast chakras that revealed strange everywhere with a puzzled gaze.

The source of this tailed beast chakra is a crane guarding the sand in the shade.

Shiraishi felt that this kind of chakra had very high research value, so when he was on the run, he easily used an experimental bottle that could automatically absorb chakra to get a little back.

The preliminary analysis of the tailed beast Chakra, Shiraishi already almost understood.

It's just something deeper, and there is still a lack of an effective way to explore and decipher.

The most important thing is that although he is proficient in the nature changes of the yang attribute, he is not very proficient in the nature changes of the yin attribute.

And the spiritualization technique that Liuli handed over to him before also belongs to the type of ninjutsu that changes the nature of the Yin Attribute Chakra, which can ignore any defense and enter the enemy's spiritual world for destruction and control.

Therefore, if you want to explore the secret of the tailed beast chakra, the premise is that you must be proficient in the nature changes of yin and yang attributes.

Just as Shiraishi was thinking, the door to the laboratory above opened, and the sound of footsteps came from far and near.

A petite figure slowly descended the stairs of the passage.

"Are you back? That's a long time. ”

Shiraishi saw that it was Liuli who came back, and teased her.

"You said it was right."

Ruri said this.

Bai Shi was slightly stunned, and then supported his chin with his palm, looking like he was thinking seriously.

"I see, the Hokage faction is ready to exchange the rest of the benefits for the Uchiha not to pursue this matter. And the Uchiha's higher-ups vetoed your proposal, when this incident never happened, did it? ”

After he finished speaking, a handful of kunai flew towards his face.

Shiraishi used two fingers to clamp it, easily caught the flying kunai, hooked the handle ring, and put it on his fingers to play around.

He leaned slightly against the experimental table behind him, smiled and said, "The reaction is too cold, didn't I already say it?" While the Uchiha clan as a whole will benefit, the handling of the matter will not be personally satisfying. Politically, compromise is needed to maintain balance. When one side no longer accepts compromise, then blood needs to be shed. ”

And neither the Uchiha nor the Konoha higher-ups have any intention of doing such a thing.

"Your crow's beak is a real glow."

"After all, you are a staunch strengthist, and power is brought by power, not by politics for profit. As far as you are concerned, as long as you have the strength, whether you want to grab things or fight for them, you will not be able to accept the use of compromise to make profits. That's where the biggest disagreement between the two of you lies. ”

Ruri looked at Shiraishi with a little disgust.

I always felt like I was being seen through by him stripped naked.

"But I think it's actually a ploy for the Uchiha higher-ups to do this. You must know that the Uchiha clan is not a small family, politics, economy, and military are originally a trinity, indispensable, and politics is inherently untidy and chaotic......"

"Long-winded, I'm not here to listen to your tirade here."

In the face of Liuli's tough attitude, Baishi didn't say anything, just spread his hands innocently, expressing his helplessness.

"Okay, that's all for that. Let's change the subject, I have something to ask you for help with. ”

Shiraishi was already very skilled in asking Ruri to do something, and there was no embarrassment on his face.

"What?"

"I want to collect information on tailed beasts. There should be more information about this in the Uchiha clan, right? ”

"Yes, yes, you want this ......"

Speaking of this, Liuli glanced at the glass pillar in the detection instrument next to her, which was sealed with a cloud of entity chakra that emitted a light purple light.

"Chakra of Shouzuru?"

Ruri understood Shiraishi's intentions.

"Ah, yes, don't you think the power that guy exerted that day was very impressive? And I think that the tailed beast and my research are actually the same way, and there are probably some parts in common. If you can get more information about the tailed beast, or chakra......"

Shiraishi is talking here eloquently, not caring to tell Ruri that the tailed beast chakra is very valuable for research.

As for whether it is related to his research, only he knows.

"I can get you the information, but you don't have to think about this kind of thing. Human power is the core secret of every village, and unrelated people will not be allowed to come into contact. ”

"That's right."

Shiraishi was not disappointed, and was already satisfied to be able to get more information about the tailed beast.

However, what he said before did not deceive Ruri.

The tailed beast Chakra, and his experimental research, do have a lot of resonance.

Especially natural energy.

"In addition, I also need detailed information on the changes in the nature of the Yin Attribute Chakra, so please do this."

After making a request for information on the tailed beast, Shiraishi went on to make a second request.

The Tailed Beast Chakra contains the changes in the nature of the Chakra of the Yin and Yang attributes, and if you really want to understand the secret of the Tailed Beast, there is nothing wrong with the premise of learning the changes in the nature of the Chakra of the Yin and Yang attributes.

Ruri suddenly wanted to step on the other party's smiling face a few times.

What did you think of her? Withdrawal tool man?

"That's right."

Shiraishi thought of something again, and suddenly said.

Ruri's brow couldn't help but wrinkle.

"What else?"

"When you reported to Orochimaru Kamishinobi that day, did you have any explanation about the tailed beast?"

Sand Yin is secretly preparing to use the Tailed Beast weapon, which is not a joke.

"There's no need. If we hadn't known in advance that Moritsuru was sealed there, the Root Ninja wouldn't have misled us into going there. The Konoha ninjas on the front line have already gotten the news. What's more, seeing that the troops pursuing us failed, it is also unknown whether Shagakure will use the power of Shouhe. ”

Ruri thought for a moment and answered Shiraishi's question.

"That's right...... No problem. ”

"If something like this happens, the village should be cold to us for a long time, you have enough time to do research, don't waste this free period."

"Of course, speaking of which, I really have to thank those people at the roots."

Shiraishi said with a smile on his face.

Give them a super gift later. I quietly added this sentence in my heart.

◎

As Ruri said, in addition to the captain Qimu Shuomao's normal mission, the three of them all received leave notices.

Due to the ineffective handling of the dark department, which led to an accident in the mission, in order to shock the three of Shiraishi, a two-month vacation was specially granted for rest.

This is an official notice from the Hokage's official letter, which probably means so.

Shiraishi glanced at it and didn't pay any more attention to it.

This also gives him plenty of time to deal with research matters.

He had so much research to do.

Yin attribute chakra nature change cultivation, immortal arts, spiritualization techniques, verify whether the loss of chakra in the human body is equal to death, tailed beast chakra...... Wait a minute.

There are a lot of things in hand, and in just two months, in Shiraishi's opinion, it is still a little too rushed.

But fortunately, many experiments can be carried out at the same time, so there is no delay.

For example, the immortal experiment, as well as the experiment to verify whether the human body loses the chakra and dies, can all be carried out at the same time.

He could also master the Spiritualization Technique as soon as possible while cultivating the Yin Attribute Chakra Nature Change Technique.

And the price is that in addition to eating and sleeping every day, he will always soak in the laboratory, doing research and cultivation.

Mastering the changes in the nature of the Yin Attribute Chakra is not difficult for Shiraishi.

When I first learned the changes in the nature of the Yang Attribute Chakra, it didn't take long, and the same degree of Yin Attribute Chakra Nature Changes were naturally not a problem.

It only took less than a week for Shiraishi to grasp the change in the nature of the Yin Attribute Chakra.

After mastering it, Shiraishi also deliberately asked Ruri to teach him a simple basic illusion - Narakumi no Jutsu.

An illusion that allows the enemy to see the most terrifying things in their hearts.

This can be said to be an entry-level illusion.

Learning this illusion is not for the sake of fighting against the enemy, but for the purpose of learning the art of spiritualization, and to warm up in advance.

Compared to the basic illusion technique of Narakumi, which involves the spiritualization technique at the soul level, the difficulty of learning is infinitely higher.

So Shiraishi didn't plan to do it overnight from the beginning, and in fact, he didn't have the talent to learn S-class arcane ninjutsu at a glance.

Besides, if you learn S-level arcane ninjutsu at a glance, there is no such person in the world.

In any case, if there really is such a person, it is too exaggerated.

Even the copying ability of the Writing Wheel Eye cannot do this.

After a few more days, Shiraishi finally touched the threshold of the Spiritualization Technique.

Although he only touched a little threshold, Shiraishi also felt that he had benefited a lot.

Spiritualization is not only capable of using one's own spirit body to exercise mind control over enemies, but also has the ability to squeeze out other people's spiritual worlds and destroy them.

Since it can lock onto targets from a long distance, it also has a wide range of perception capabilities, and its locking ability is very good.

Shiraishi now only needs to seal and let go of his mind, and he can sense everything within a radius of twenty meters around him.

This kind of ninjutsu, which seems to have opened up a god's perspective to himself, makes Shiraishi more confident in the future research of tailed beasts.

Shiraishi's goal is very clear, whether it is the basic illusion technique Narakumi or the spiritualization technique, the purpose is to further explore the changes in the nature of the Yin attribute chakra and serve his research institute.

Just as Shiraishi was using his consciousness to perceive the outside world unimpeded, he suddenly had a tingling pain in his head, as if there were constant signals of warning, so he hurriedly interrupted Chakra and gave up continuing to perceive the outside world.

"Whew...... Only eleven seconds? It's worthy of the S-level ninjutsu on the Book of Seals, and with my current ability, I can't use it freely at the elementary stage alone. ”

Shiraishi can only initially perceive the outside world now, and can't even lock on to the target at a long distance, let alone use the spirit body to attack the spiritual world of the target, or manipulate the enemy's mental world more complexly.

It is far from the completion of the spiritual art of the body, and this achievement is far from the level of complacency.

Moreover, there is a huge risk that this spiritual technique will fall into a state of immobility and defenselessness when sensing and attacking the spirit.

Therefore, when there are safe and reliable teammates around, this ninjutsu can be performed smoothly.

At the same time, the longer the spirit is away from the body, the farther away, the more chakra is needed.

Although it is very capable, it is also quite cumbersome to apply.

It's a double-edged sword for the caster.

Fortunately, Shiraishi learned this ninjutsu mainly to further understand the changes in the nature of the Yin Attribute Chakra and to serve the research.

Even if the Spiritualization Technique is a chicken rib in actual combat, as long as the research value is extremely high, for Baishi, the benefits outweigh the disadvantages.

Just then, the voice of a test subject was heard from the other side:

"Lord Shiraishi, the experimental data has been updated."

The five test subjects have been able to follow Shiraishi's ideas and follow him.

Although it looks incredible, the physical fitness of the five of them is far beyond that of ordinary people, and with just a few punches and kicks, they can defeat a normal level of shinobi.

Therefore, the five of them were not only Shiraishi's valuable test subjects at this time, but also Shiraishi's safe and reliable experimental assistants.

When Shiraishi was studying the art of spiritualization, the five of them were to conduct experiments according to the steps written by Shiraishi in advance.

Bai Shi cleaned up his mood and walked over to take a look, the computer screen displayed the data of multiple fusion of immortal arts, and the 37% success probability was extremely eye-catching.

Although the body data of Liuli's previous trial of immortal art was collected, including the negative and positive effects of immortal chakra on the human body, this probability of success still made Shiraishi not very satisfied.

Compared with before, there has indeed been a great improvement, but this probability is not enough to make Baishi immediately start practicing immortal arts.

Liuli can be said to have succeeded in trying out the immortal arts, or it can be said to have failed, the success lies in the success of letting the immortal magic be released, and the failure lies in the fact that the immortal chakra rioted in Liuli's body after that.

It has a certain reference value, but it cannot be regarded as correct.

"Lord Shiraishi, this is the highest fusion value so far."

Seeing the look of dissatisfaction on Shiraishi's face, one of the test subjects whispered.

"I don't mean to blame you, after all, I arranged the steps. Looks like I need to think differently. Forget it, what was the result of experiment 2? ”

Experiment 2 refers to the experiment that verifies whether the lost chakra is dead.

Hearing Shiraishi's question, another test subject in charge of Experiment 2 said, "The mice that were put into the experiment are almost dead, but there is one mouse that is very strange......"

"Strange?"

Shiraishi walked over to take a look, only to see a mouse twitching desperately in the glass cover, and even if it was pulled away from the chakra, it did not die immediately.

Shiraishi observed with interest.

Although the mouse looked dying, it was true that it did not die immediately after extracting the chakra from its body.

"What's going on?"

The subject touched his head embarrassedly and said embarrassedly, "It's all because I accidentally took the wrong syringe and injected this mouse with something else......

As soon as he finished speaking, the body of the mouse in the glass cover stopped twitching and died motionless.

Shiraishi picked up the syringe that had been injected incorrectly, and there was still the residue of the medicine in it.

Shiraishi stared at the syringe twice, and said in a low voice, "Vitality potion......

The main ingredient of this vitality elixir is specially processed to provide natural energy for the living body to absorb.

Shiraishi looked weird.

It wasn't that he hadn't thought of replacing chakra with natural energy before, as a life energy supply to the experimental mice.

But as a result, the hundreds of mice died without exception after the chakra was withdrawn.

After that, he did not use natural energy to replace Chakra for experiments, but started with the connection between Chakra and the human body.

So what's going on now?
